ABRAHAM HORN, OF BUKAOZOWGE, AUSTRIA-HUNGARY.

SNOW-PLOW.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed April 3, 1908'. Serial No. 425,021.

To all whom it may concern:

Be it known that I, ABRAHAM HORN, a subject of the Emperor of AustriaHungary, and residing at Bukaczowce, in the Province of Galicia and the Empire of Austria-Hungary, have invented new and useful Improvements in Snow-Flows, of which the following is a specification.

This invention relates to a snowplow which is employable for railways, street or the like in combination with an engine, auto or other vehicle; the essential feature of the invention being the arrangement of several plow shares and guiding plates, situated one upon another, between which enters the snow when set going being then divided and finally expelled to the side by pressure of the following snow masses.

In the accompanying drawing Figure 1 shows the plow in sectional view on the line A-A of Fig. 2, Fig. 2 a plan, Fig. 3 a plan of another form of construction.

The shares a on the front of the plow are shaped like leaves arranged one upon another and separated by suitable interspaces. They are placed almost horizontally and continue to rising guide plates f and end once more in horizontal pieces 6, the single shares a increasing by degrees to the backs, forming sharp edges and being also pointed to the front. The fore ends of the leaves are set a little back against downward. The middle parts f have on both sides cross walls 1) provided with openings 9 and a middle wall 5. The back pieces h widen themselves in e on both sides and have wedgeshaped walls 0, forming the continuation of the wall I), and ending on both sides in parallel planes i. The extension 6 of the under surfaces are a little shortened in comparison to these, which are situated above them. The dip of the middle piecesf is chosen so that the horizontal end piece is situated higher than the foremost part wof the uppermost share; and that for the purpose of carrying off the snow in a level, which is higher than the surface of snow.

The effect of the plow is the following: When the plow is advancing the snow enters through the pieces a in several couches between the leaves and when continuing the movement by the'snow pressing after, it is pressed between the rising pieces f in two groups on both sides of the interspace 5, until it comes on the part 6 which is situated the most backwards. Here then it is pressed aside along both wedge surfaces 0 until it is thrown from the railway or the street. Taking up the quantities of the snow in layers, the plow on one side will be discharged, so that its advancing requires a small force. The turning off of the snow through the rising part allows a transportance in a level situated higher than those of the fallen snow. Hereby is provided that the snow of the upper couches falls always more outwards, than those of the lower. The driving in of the plow into the snow mass is facilitated by the deformation of the fore-leaves To be in position to vary the couches for different levels of the snow, the single plowshares respectively the leading plates are mounted in such a manner that they eventually could be taken off. To carry away the snow only partially there is employed instead of the wedge surface only one oblique leading plate 0 (Fig. 3) which eventually may be arranged turnable around a middle vertical axle.

This plow can be put before an engine (10- comotive), before an automobile or before any other motor vehicle.

Having now described my invention what I claim is:

In a snow plow, the combination with a supporting truck, of a horizontally disposed bank of shovels arranged in superposed relation and tapering laterally to points at their forward end, the points of said shovels receding from the uppermost to the lowermost shovels, a bank of inclined passageways closed at their sides, top and bottom and open at their ends, said passageways registering with said shovels at their forward ends and gradually increasing in size from their forward to their rearward end, a longitudinally disposed partition dividing said passage-ways into separate lateral compartments, a bank of horizontally disposed chambers to which said passageways deliver, a plurality of leaves 6 extending laterally from said chamber, and deflecting walls for each chamber converging to said partition.

In testimony whereof I afliX my signature in presence of two witnesses.

ABRAHAM HORN.
